Intro to Earth Science
The study of the universe, planets, and stars.
What is astronomy?
What is the Milky Way galaxy?
The model of the solar system that states the Earth is at the center of the Universe.
What is the Geocentric Model?
This theory states that the universe began as an infinitely hot and dense point.
What is the Big Bang Theory?
The point at which a planet is furthest away from the Sun in its orbit.
What is aphelion?
The sphere of Earth that includes the layer of gasses surrounding the Earth.
What is the atmosphere?
The third planet from the Sun.
What is Earth?
Johannes Kepler discovered that planets orbit the sun in this non-concentric shape.
What is an ellipse?
A cloud of gas and dust in space.
What is a nebula?
The invisible force that holds planets and other bodies in orbit.
What is gravity?
The study of Earth's structure, materials, and processes, including rocks, minerals, plate tectonics, and earthquakes.
What is geology?
Jupiter
The heliocentric model states that planets in the solar system orbits around this planetary body.
What is the sun?
The leading theory for the formation of our solar system 4.6 billion years ago.
What is Solar Nebular Theory?
The point at which a planet is closest to the Sun in its orbit.
What is perihelion?
The sphere of Earth that includes all of Earth's water including oceans, rivers, lakes, glaciers, and groundwater.
The shape of the Milky Way Galaxy.
What is spiral?
This astronomer was credited with proposing the Heliocentric Model of the Universe.
Who is Copernicus?
One of the first two gasses present in the universe.
What is hydrogen or helium?
The center of gravity between two orbiting objects.
What is barycenter?
The sphere of Earth that includes all living organisms on Earth.
What is the biosphere?
The Supercluster that the Milky Way Galaxy is located in.
What is the Laneakia Supercluster?
This astronomer first proposed the geocentric model in the 2nd century.
Who is Ptolemy?
The small irregularly shaped planetary bodies that would later form our sun, planets, and moons.
What are planetesimals?
Earth rotates in this direction.
What is counterclockwise?
